## Title
Network connector socket

## Abstract

A network connector socket includes an insulated body, first contacts, and second contacts. Each first contact includes a first fixed segment fixed in the insulated body. The first fixed segments are arranged in parallel on a first plane. Each second contact includes a second fixed segment fixed in the insulated body. The second fixed segments extend on a second plane spaced apart with the first plane and are arranged in parallel. One of the first fixed segments is bent and extends to cross at least one of the second fixed segments. For one of the first contacts, the corresponding first fixed segment has a larger transverse width than that of the rest. For one of the second contacts, the corresponding second fixed segment has a larger transverse width than that of the rest. Thus, the crosstalk noise between the contacts is reduced by capacitive compensation.

The first fixed segments 211/221/231/241 are fixed in the insulated body 100 by means of the insert molding of the insulated body 100. The first fixed segments 211/221/231/241 are arranged in parallel on a first plane 201 and coplanar with each other, whereby to fix the first contacts 210/220/230/240. The first fixed segments 211/221/231 of some first contacts 210/220/230 are exposed to a recess 110 of the insulated body 100. In the current embodiment, two ends of each of the first fixed segments 211/221/231 of the three first contacts 210/220/230 bend and extend on the first plane 201; one end of the first fixed segments 221 of the first contact 220 bends and extends on the first plane 201. For the first contact 220, the first fixed segment 221 has a larger transverse width than that of the rest. The first clamping segments 212/222/232/242 are configured in such a manner that they extend from the corresponding first fixed segments 211/221/231/241 and bend by 90 degrees. The first welding segments 213/223/233/243 are for being welded to a PCB such that the network connector socket of the present invention is electrically connected to the PCB.

The second fixed segments 311/321/331/341 are arranged in parallel on a second plane 301 and coplanar with each other, whereby to fix the second contacts 310/320/330/340. The second fixed segments 321/331/341 of some second contacts 320/330/340 are exposed to a recess 120 of the insulated body 100. In the current embodiment, two ends of each of the second fixed segments 311/321/341 of the three second contacts 310/320/340 bend and extend on the second plane 301; one end of the second fixed segments 331 of the second contact 330 extends straight on the second plane 301. For the second contact 330, the second fixed segment 331 has a larger transverse width than that of the rest. The second clamping segments 312/322/332/342 are configured in such a manner that they extend from the corresponding second fixed segments 311/321/331/341 and bend by 90 degrees. The second welding segments 313/323/333/343 are for being welded to the above-mentioned PCB such that the network connector socket of the present invention is electrically connected to the PCB. In the current embodiment, the second welding segments 313/323/333/343 of the second contacts 310/320/330/340 are configured in such a manner that they extend from the corresponding second fixed segments 311/321/331/341 and bend by 90 degrees; however, the present invention is not limited to this. The configuration of the second welding segments 313/323/333/343 can be changed according to the configuration of the network connector socket disposed on the PCB. For example, the second welding segments 313/323/333/343 and the second fixed segments 311/321/331/341 can also be disposed on the same plane.
In the current embodiment, three bent extended first fixed segments 211/231/241 are disposed corresponding to three bent extended second fixed segments 311/321/341, respectively. Two corresponding segments 211/311 or 231/321 or 241/341 bend in opposite directions such that two crosses are formed between the two corresponding segments. The first fixed segments 211 and the second fixed segment 311 cross mutually and are both disposed at one side of the first fixed segment 221 having a larger transverse width; the first fixed segment 231 and the second fixed segment 321 cross mutually and are disposed at the other side of the first fixed segment 221 having the larger transverse width.

Please refer to FIG. 1. In the current embodiment, the housing 400 is preferably a hollow rectangular parallelepiped made of plastic. One side of the housing 400 has a receiving port 410 into which the network connector socket can be plugged. A positioning pin 420 protrudes from another side of the housing 400. In the current embodiment, there are two positioning pins 420; however, the number of the positioning pins is not limited. The positioning pins 420 are used to latch a PCB such that the network connector socket of the present invention can be fixed to the PCB. The insulated body 100 is received in the housing 400. The first clamping segments 212/222/232/242 and the second clamping segments 312/322/332/342 are disposed corresponding to the receiving port 410. When the network connector socket is plugged into the receiving port 410, The first clamping segments 212/222/232/242 and the second clamping segments 312/322/332/342 can contact and electrically connect to the network connector socket, thus enabling the network connector socket to electrically connect to the PCB.
The first welding segments 213/223/233/243 and the second welding segments 313/323/333/343 protrude out of the housing 400. The first welding segments 213/223/233/243 and the second welding segments 313/323/333/343 are arranged alternately in parallel and coplanar with each other. The first clamping segments 212/222/232/242 are arranged in parallel along a first row and the second clamping segments 312/322/332/342 are arranged in parallel along a second rows, in which the first and second rows are in parallel to each other. The positioning pins 420 extend in the same direction as those of the first welding segments 213/223/233/243 and the second welding segments 313/323/33/343.
The present invention uses a cross configuration of the first contacts 210/230/240 and the second contacts 310/320/340 to produce a capacitive compensation effect in between; thus, the crosstalk noise between the first contacts 210/230/240 and the second contacts 310/320/340 can be reduced. In addition, the transverse width change of the first contact 220 (or the second contact 330) in conjunction of its adjacent first contact 210 or 230 (or the second contact 320 or 340) produces another capacitive compensation effect, which reduces the crosstalk noise between two adjacent first contacts (or second contacts). Further, the first contacts 210/220/230 (or second contacts 320/330/340) are exposed to the recess 110 (or 120) of the insulated body 100, which can change the medium, i.e., plastic is changed to air, between two adjacent parts of the first contacts (or the second contacts); thus the crosstalk noise between the two adjacent parts of the first contacts (or the second contacts) can be reduced by the capacitive compensation effect generated in between.
The embodiments described above are only preferred ones of the present invention and not to limit the scope of appending claims regarding the present invention. Therefore, all the equivalent modifications applying the spirit of the present invention should be embraced by the scope of the present invention.
